SGRAP-BUNDLING MACHINE.

Specification of Letters Patent.

' PatentedFeb.8,1916.

Application filed March 24, 1914. Serial No. 826,863.

Be it known that I, DAVID B. MARWIGK, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Scrap- Bundling Machines, of which the following is a specification.

My invention relates to machines for making metal and other resistant scrap material into compact bundles for easy transportation and handling and my objects are the production of amachine which will besmall in size, free from mechanical complications and from which the formed bundle may be easily removed. Heretofore such machines have been provided with solid formers from which the mandrel has been removed endwise to release the bundle, necessitating a floor space approximately double that occupied by the machine. My improved machine requires no addi-tional floor space for this purpose and automatically loosens the bundle on the mandrel after forming.

In the drawings Figure 1 is a front view of the machine, Fig. 2 a top view, Fig. 3 a sectional View on the line 33 of Fig. 1 with the frame open for the removal of a bundle, Fig. 1 a sectional view on the line 44 of Fig. 1 and Fig. 5 a sectional detail on the line 55 of Fig. 1.

The machine comprises a mandrel 1, preferably squared and tapered, on a suitable frame 2, and is rotated by any desired mechanism. This mandrel is provided with a strand engaging device 3, the simplest form being a slot in the mandrel. The squared form of mandrel is preferred on account of the increased efficiency of the corners in winding up the scrap.

The bundle former consists of a frame surrounding the mandrel. As shown in the drawings this former comprises two sections 4 and 5 hinged to the frame at 6 and 7. The free ends of the sections have the semi-circular bearings 9 and 10 to support the free end of the mandrel while the bundle is being formed. The frame 2 extends into the former at 11 to fill the cut out portions 12 and 13 of the latter, presenting a smooth, unbroken interior surface when the sections are closed.

Any suitable locking device may be used to hold the former sections together but I prefer a device which will not only perform this function but will also force the sections apart when removing the bundle for the reasons hereinafter set forth. Such device is shown in the drawing in' which 14 is an arm extendin'gfrom the frame 2 carrying at its outer end the lever 15 fulcrumed at 16. A link 17 connects the former section t to the lever 15 and a second link 18 connects the former section 5 to the lever 15. It is apparent that on pullingthe lever 15 the parts will assume the positions shown in dotted lines in Fig. 2 and the former sections will be forced apart so that a bundle can be removed endwise of the mandrel. As

the former sections are forced apart the portions 19 and 20 will bear against the side of the bundle and force the same longitudinally of the mandrel thereby freeing its grip thereon, after which the bundle may be easily removed from the mandrel by a locked and the mandrel rotated. A strand of scrap is pushed into slot 3 and the rotation of the mandrel will wind it around the mandrel. Additional scrap is fed and entangles itself with that already wound until the former is filled and the bundle sufiiciently compacted. The former sections are then unlocked and pushed apart thus start ing the bundle on the tapered mandrel, after which it can be easily slipped off the end.

I claim i 1. In a scrap bundling machine, a frame, a mandrel thereon, means for rotating the mandrel and a bundle former surrounding the mandrel and hinged to the frame, said former comprising a plurality of sections each of which is adapted to completely encircle the bundle whereby a bundle may be removed from the mandrel by a direct longitudinal pull when the former is open.

2. Ina scrap bundling machine, a frame, a mandrel thereon, means for rotating the mandrel, a bundle former surrounding the mandrel, said former comprising a plu rality of sections movable with respect to the mandrel, and means whereby a bundle will be moved longitudinally of the mandrel .on opening the former sections.

1. s rap undling machine, a fra a mandrel thereon, means for rotating the mandrel, a bundle former surroundlng the .mandrel, said former consisting of a plu- 'mandrel, former surrounding the mandrel comprising tWo sections hinged to the frame at one side, means engaging the other side of'each section for locking them together and for forcing them apart, and projections on the inner faces of each section, adjacent to the hinges for longitudinally moving a bundle on the mandrel on opening the former.

5. In a scrap bundling machine, a frame,

a mandrel thereon, means for rotating the mandrel, a bundle former surrounding the mandrel, said former comprising a plurality of sections hingedto the frame at one side and engaging the free end of the mandrel at the other side to support the same during the formation of a bundle.

6. In a scrap bundling machine a frame, a mandrel thereon, means for rotating the mandrel and a solid bundle former completely surrounding the mandrel and com pletely encircling the bundle during formation and movable With respect to the mandrel to permit Withdrawal of the formed bundle by a direct longitudinal pull.

In testimony whereof I have affixed my signature in presence of two Witnesses.
